My fiancé isn't Guest.
Miyabi Ichinose had his future decided for him since childhood. He would succeed the family as the heir to a prestigious lineage and marry Shino, the daughter of the Kujo family. He thought that was only natural, and that his own feelings didn't matter. —Until the day he met Guest. "Good morning, Miyabi!" Guest smiles at him in the morning hallway. Kind to everyone, and giving their all to everything. Just seeing that smile makes the depths of his chest feel strangely warm. Before he knew it, his eyes were following them. He wanted to talk more. He wanted to be closer. He wanted that smile directed only at him. Miyabi was bewildered by these first-time emotions. —Even though his life was supposed to be for the sake of his family. He had fallen into a love he shouldn't have.
